name: argocd-cli description: Complete ArgoCD CLI and REST API skill for GitOps automation. Use when working with ArgoCD for: (1) Managing Applications - create, sync, delete, rollback, get status, wait for health, view logs, (2) ApplicationSets - templated multi-cluster deployments with generators, (3) Projects - RBAC, source/destination restrictions, sync windows, roles, (4) Repositories - add/remove Git repos, Helm charts, OCI registries, credential templates, (5) Clusters - register, rotate credentials, manage multi-cluster, (6) Accounts - generate tokens, manage users, check permissions, (7) Admin operations - export/import, settings validation, RBAC testing, notifications, (8) Troubleshooting - sync issues, health problems, connection errors. Supports both REST API (curl/HTTP) and CLI approaches with bearer token authentication.

ArgoCD Skill

Complete ArgoCD operations via REST API and CLI with bearer token authentication.

Authentication Setup

Generate and use bearer tokens for all operations:

# Generate token (requires existing login)
argocd login $ARGOCD_SERVER --username admin --password $ARGOCD_PASSWORD
ARGOCD_TOKEN=$(argocd account generate-token)

# Or generate for service account
ARGOCD_TOKEN=$(argocd account generate-token --account cibot --expires-in 7d)

# Export for subsequent commands
export ARGOCD_SERVER="argocd.example.com"
export ARGOCD_AUTH_TOKEN="$ARGOCD_TOKEN"

Service account setup (in argocd-cm ConfigMap):

data:
  accounts.cibot: apiKey,login
  accounts.cibot.enabled: "true"

REST API Pattern

All API calls use this pattern:

curl -s -H "Authorization: Bearer $ARGOCD_AUTH_TOKEN" \
  -H "Content-Type: application/json" \
  "https://$ARGOCD_SERVER/api/v1/{endpoint}"

Use the helper script at scripts/argocd-api.sh for common operations.

Error Handling

# Check if app exists before operations

  argocd app sync myapp
else
  argocd app create myapp ...
fi

# Wait with timeout and handle failure
if ! argocd app wait myapp --health --timeout 300; then
  echo "App failed to become healthy"
  argocd app get myapp
  exit 1
fi

# Idempotent upsert pattern
argocd app create myapp --upsert ...
argocd repo add https://repo --upsert ...

Common Workflows

Deploy and Wait Pattern

argocd app sync myapp --prune --async
argocd app wait myapp --health --sync --timeout 300

Canary/Blue-Green with Argo Rollouts

# Promote rollout
argocd app actions run myapp promote --kind Rollout --resource-name my-rollout

Multi-Cluster Deployment

# Register clusters
argocd cluster add dev-context --name dev
argocd cluster add prod-context --name prod

# Use ApplicationSet with cluster generator

Admin Operations

# Get initial admin password
argocd admin initial-password -n argocd

# Export all resources for backup
argocd admin export > backup.yaml

# Import from backup
argocd admin import < backup.yaml

# Start local dashboard (core mode)
argocd admin dashboard

# Validate RBAC policy
argocd admin settings rbac validate --policy-file policy.csv

# Test RBAC permission
argocd admin settings rbac can role:developer sync applications 'myproject/*'

# Notification management
argocd admin notifications template list
argocd admin notifications trigger list

Troubleshooting Quick Reference

# Check diff for out-of-sync apps
argocd app diff myapp

# Force refresh from Git
argocd app get myapp --hard-refresh

# View detailed sync operation
argocd app get myapp --show-operation

# Check application conditions
argocd app get myapp -o json | jq '.status.conditions'

# Terminate stuck sync
argocd app terminate-op myapp

# Check controller logs
kubectl logs -n argocd -l app.kubernetes.io/name=argocd-application-controller --tail=100

# Apps not healthy
argocd app list -o json | \
  jq -r '.items[] | select(.status.health.status != "Healthy") | .metadata.name'

# Apps out of sync
argocd app list -o json | \
  jq -r '.items[] | select(.status.sync.status != "Synced") | .metadata.name'
